摘要： A bearing housing includes inner and outer shells through which a rotor shaft may extend. A service tube is fixedly joined to the inner shell and extends through a service aperture in the outer shell. A flexible coupling sealingly joins the service tube to the outer shell at the service aperture for permitting differential thermal movement between the inner and outer shells at the service tube.

摘要： A retainer for non-rotatably retaining a conduit member that extends through an opening in a casing wall. The retainer has an annular top wall that includes an inner periphery having inwardly extending projections to engage the outer surface of the conduit member. Additionally, the retainer includes a depending skirt that extends from the outer periphery of the top wall. A pair of outwardly extending straps extend from the skirt and include bolt holes for enabling the retainer to be bolted relative to the casing wall. The retainer limits axial outward movement of the conduit member and also diffuses and deflects any leakage air that passes around the conduit member to avoid impingement of the leakage air against the structural components and accessories that are positioned outside the engine casing.

摘要： An exemplary method of designing a manufacturing process comprises the steps of representing a workpiece as a plurality of triangular finite elements, representing the forming tools with mathematical equations which typically include cubic polynomials, simulating a deformation of the workpiece by the forming tools with a finite element model, wherein the finite element model is integrated with explicit integration. The method may be carried out with an apparatus which includes a memory device which stores a program including computer readable instructions, and a processor which executes the instructions. After the deformation of the workpiece has been simulated by the finite element model, the characteristics of the workpiece and forming tools can be modified to improve the final shape of the workpiece. After the finite element simulation produces an acceptable final workpiece shape, an actual workpiece can be formed with actual tools based on the simulation.
